ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

The Surface 3 is not following the ACPI spec for PNP0C40, but nearly.
The device is connected to a I2C device that might have some magic
but we don't know about.
Just create the device after the enumeration and use the declared GPIOs
to provide button support.
This driver is just an adaptation of drivers/input/misc/soc_button_array.c
The Surface Pro 3 is using an ACPI driver and matches against the bid
of the device ("VGBI"). To prevent this incompatible driver to be used
on the Surface Pro, we add a match on the Surface 3 bid "TEV2".

The LID state provided by ACPI on the Surface 3 is not accurate.
The ACPI node doesn't get notified on LID open, which means the
LID input switch stays close most of the time.
Fortunatelly, there is a WMI method which directly queries the
GPIO underneath the LID state, so it's far more reliable than ACPI.
To get the notifications that the LID was opened/closed, we can
rely on the ACPI notification of the touchscreen: the DSDT shows
that the touchscreen will get notified on close/open as it also
controls its _STA method.
Note that we need to set the tag "power-switch" to the LID
input node through a udev rule for logind to accept it:
SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="surface3-wmi", \
TAG+="power-switch"

The hotkey events and ACPI handles used for detecting tablet mode on a
few of the newer thinkpad models (Yoga X1 and the Yoga 260 specifically)
have been changed around, so unfortunately this means we're definitely
going to need to probe for multiple types of tablet mode support. Since
the hotkey_init() is already a lot larger than it should be, let's split
up this detection into its own function to make things a little easier
to read.
As well, since we're going to have multiple types of tablet modes, make
hotkey_tablet into an enum so we can also use it to indicate the type of
tablet mode reporting the machine supports.

The PCH implements a number of High Speed I/O (HSIO) lanes that are split
between PCIe*, USB 3.0, SATA, GbE, USB OTG and SSIC. This patch shows the
current power gating status of the available ModPhy Core lanes. This is
done by sending a message to the PMC (MTPMC) that contains the XRAM
register offset for the MPHY_CORE_STS_0 and MPHY_CORE_STS_1 and then by
reading the response sent by the PMC (MFPMC).
While enabling low power modes we often encounter situations when the
ModPhy lanes are not power gated and it becomes hard to debug which lane is
active and which is not in the absence of an external hardware debugger
(JTAG/ITP). This patch eliminates the dependency on an external hardware
debugger for reading the ModPhy Lanes power gating status.
This patch requires PMC_READ_DISABLE setting to be disabled in the platform
bios.

debugging purpose while tuning the platform for power optimizations and
also to understand which devices (on PCH) are blocking the system to enter

Power Management Controller on Sunrise Point PCH provides access to "PGD

this register and dumps the output in formatted manner showing various

The AMW0_GUID1 wmi is not only found on Acer family but also other
machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled
those non-Acer machines by quirks list.
But actually acer-wmi driver was loaded on any machine that had
AMW0_GUID1. This behavior is strange because those machines should be
supported by appropriate wmi drivers. e.g. fujitsu-laptop,
ideapad-laptop.
This patch adds the logic to check the machine that has AMW0_GUID1
should be in Acer/Packard Bell/Gateway white list. But, it still keeps
the quirk list of those supported non-acer machines for backward

they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

Enable system support for the Mellanox Technologies hotplug platform
driver, which provides support for the next Mellanox basic systems:

"msb7800", "msn2740", "msn2100" and also various number of derivative
systems from the above basic types.
This driver handles hot-plug events for the power suppliers, power
cables and fans for the above systems.
The Kconfig currently controlling compilation of this code is:

Bug 150611 uncovered that the WMI ID used by the toshiba-wmi driver
is not Toshiba specific, and as such, the driver was being loaded
on non Toshiba laptops too.
This patch adds a DMI matching list checking for TOSHIBA as the
vendor, refusing to load if it is not.
Also the WMI GUID was renamed, dropping the TOSHIBA_ prefix, to
better reflect that such GUID is not a Toshiba specific one.

This particular laptop has its motherboard replaced and after that, even
with the latest BIOS, some DMI identification strings have become
"INVALID". This includes DMI_PRODUCT_VERSION which results Wifi being
blocked.
It seems that DMI_BOARD_NAME is still valid so use that as an
alternative for Lenovo Yoga 900.

A recent bugfix added a call to i8042_install_filter but did
not add the dependency, leading to possible link errors:
drivers/platform/built-in.o: In function `asus_nb_wmi_quirks':
asus-nb-wmi.c:(.text+0x23af): undefined reference to `i8042_install_filter'
This adds a dependency on SERIO_I8042||SERIO_I8042=n to indicate
that we can build the driver when the i8042 driver is disabled,
but it cannot be built-in when that is a loadable module.

of trip points. Whenever the current temperature is changed, the trip
points immediately below and above the current temperature are found,

when either of the two trip points are triggered. Hardware-tracked

While looking at a patch that introduced a compile-time warning
"‘pmc_core_dev_state_get’ defined but not used" (I sent a patch
for debugfs to fix it), I noticed that the same patch caused
it in intel_pmc_core also introduced a bogus run-time warning:
"PMC Core: debugfs register failed".
The problem is the IS_ERR_OR_NULL() check that as usual gets
things wrong: when CONFIG_DEBUGFS_FS is disabled,
debugfs_create_dir() fails with an error code, and we don't
need to warn about it, unlike the case in which it returns
NULL.
This reverts the driver to the previous state of not warning
about CONFIG_DEBUGFS_FS being disabled. I chose not to
restore the driver to making a runtime error in debugfs
fatal in pmc_core_probe().

ACPI WDAT table is the preferred way to use hardware watchdog over the
native iTCO_wdt. Windows only uses this table for its hardware watchdog
implementation so we should be relatively safe to trust it has been
validated by OEMs.
